I don't really know. I never bothered to look it up. Back in 73/74 time frame, a company in St. Louis was getting rid of their old teletypes. I seem to remember they were going to the newer teletype model 43 ?? Anyway, he pointed to the ones without paper tape, and said they were ASRs and pointed to the ones with paper tape and say they were KSRs. I assumed he knew what he was talking about.
But with the paper tape models there were 5 level (bodot?) and 8 level (something). The 110 baud modem, which weighed 40-50 pounds, was most of the stand it was on. We hooked it into the phone system, which was illegal back then, and I could dial back into the mainframe (OS/VS 1 at that time) and use TSO. Printing out a listing on the teletype in my apartment was sure noisy.

I remember using one back in high school at a special program at TCU in Ft. Worth. I was impressed. Not with the KSR, but with the professor who apologized for being late - he was trading in his 2 year old Rolls Royce for a new one. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
